17 Claims. (Cl. 12-192) This invention relates to machines for use in the manufacture of shoes and is illustrated as embodied in an improved fastening inserting machine for securing insoles to the bottoms of lasts.

As disclosed in United States Letters Patent No. 1,736,276, granted November 19, 1929, on an application filed in the name of Arthur F. Pym, it has been proposed to position insoles upon the bottoms of lasts by the use of clamping members, each having two projecting pins which fit in pairs of registering holes, respectively, formed in the insole and the last bottom. After the insole has been positioned and clamped to the bottom of the last, as above described, the assembled unit is presented by hand to fastening inserting mechanism to cause tacks or other suitable fastenings to be driven through the insole and into the bottom of the last preparatory to performing various other shoemaking operations, the registering recesses in the insole and bottom of the last later being utilized to position the insole and the last in a lasting machine, as disclosed, for example, in United States Letters Patent No. 1,674,060, granted June 19,

1928, on an application filed in the name of Arthur F. Pym.

Various devices, such, for example, as disclosed in United States Letters Patent No. 1,702,364, granted February 19, 1929, on an application filed in the name of Arthur F. Pym,

and in United States Letters Patent No. 2,186,046, granted January 9, 1940, on an application filed in the name of A. R. Schoenky, have been incorporated in fastening inserting machines and are adapted to position insoles upon the bottoms of lasts and to facilitate the presentation of said positioned insoles to mechanism for driving fastenings through the insoles and into the. lasts. It has been found that although insoles can be secured more accurately to the bottoms of lasts by the use of clamping members or devices such as above referred to than by the well-known hand positioning and tacking method, such members or devices have not enjoyed substantial commercial success because of the fact that their use increases little, if any, the speed of the abovementioned operation.

It is an object of the present invention to provide a fastening inserting machine by the use of which insoles may be positioned upon and secured to the bottoms of lasts faster and more accurately than has heretofore been possible.

With the above object in View, and in accordthere is provided a fastening inserting machine comprising means for positioning an insole upon the bottom of a last, means for clamping'together the last and the insole positioned thereon, mechanism for inserting fastenings, said clamping means being mounted for movement to transfer the insoleto a predetermined position adjacent to the fastening inserting mechanism, and means for operating said mechanism to drive a fastening through the insole andinto the last. 7

The foreparts of insoles and the bottoms of the lasts are each provided with three cylindrical holes Which are of equal diameter and'are ar-.- ranged in triangular'relation, the arrangement being such that when corresponding holes formed in the last and the insole which is to be attached to the last are in registration, the insole is positioned accurately upon the last. In order to position the insole upon the bottom of the last, the illustrative machine is provided Witha work carrier an abutment of which has three pins shaped and arranged to register in corresponding holes respectively, in the insole and the bottom of the last, a gage being secured to the carrier to assist the operator in aliningthe .cor-

responding holes in the insole and thelast with the pins of the carrier, thereby facilitating'the proper assembling of the insole and the last upon the pins.

In order that the last and the insole positioned thereon as above described shall be clamped securely together and shall be held against movement in the Work carrier preparatory to and during the attachment of the insole to the last, the carrier is provided with a fluid-operated presser member which forces the forepart of the last against the forepart of the insole and the insole against said abutment. The carrier is normally held yieldingly in an idle orloading position away from the fastening inserting mechanism by suitable spring-operated mechanism, the construction and arrangement of the carrier and its supporting mechanism being such that the operator, by gripping the work, may quickly and effectively present different portions of the insole positioned upon and clamped against the last successively to the fastening inserting mechanism preparatory to driving tacks or other fastenings through the insole and into the last. By the use of the above machine insoles may be secured to the bottoms of lasts quicker and more effectively than has heretofore been possible.

Various other features of the invention will be ance with a feature of the Present invention, understood and appreciated from the following the insole is positioned and clamped; and

Fig. 3 is aperspective view, partlybroke'n away, of the last and the insole shown in Fig.2

after the insole has been tacked to the last byv the use of the above machine i W The illustrative machine is described with ref- '10 insole and into the bottom of a last upon which i erence to positioning upon and clamping against the bottomof a last I8 (Figs. 2 and 3) an insole;-

20, and thereafter tacking the insole to the last bythe use of 'well known fastening inserting mechanism 22 (Figs. 1 and 2), such, for example,

is disclosed in United States Letters Patents Nos. 1,106,393 and 1,312,557, granted August 11, 1914 and August 12, 1919, respectively, on applications filed in the-name oil Fred L. MacKenzie.

- The last I8, which is'of the type commonly used in the manufacture-of McKay shoes, for example, has; securedto its bottoma steel plate 24 (Fig. 3) provided with holes 26, 21, 28 and 29, respec-' tively, arranged along the median portion of the bottom fthe'last. The hole 26 is spacedthe same distance from the toe or toe end of the last regardless of thesize or shape of the last, and

I the "holes 21 and 28, respectively, are located at theballportion and at the break line of the last,

Inorder' quickly and accurately to position the insole" upon and to clampit securely against the ';last I8 preparatory to tacking the insole to the last, there is provided a work assembling, and supporting unit 30. (Fig. 1) which is mounted upona bracket 32 secured by one or more screws 34 to a standard 36. of themachine. The fasteningj'inserting mechanism 22 comprises a nozzle 7 I 38 (Figsgl and 2) through which tacks 40 are driven by'suitable mechanism (not shown) actuatedupon depression of a treadle (not shown) or by pressure of the insole 20 clamped in the unit 30, as will appear later, against a trip lever 42 operatively connected to a one-revolution clutch (notshown).

Passing through an elongated slot. 44 (Fig. 1) in the bracket 32 and. secured'to the bracket,

through. the provision of a nut 46, is a bearing i.

rod 481upon which is pivoted a support 58. Secured by a lock screw 52 to a reduced portion of the rod48 is aistop 54 against which the support is.held, when the machine is idle, by a. coil spring 56 one endof which embraces the support and the other end of which embraces a, stud 58 on a. collar 60 secured to the rod.

. Anruppertportion 82o'f the support 50, which is mounted forpivotalmovement about an axis 64 (Fig. 2) with relation to alower portion 66 of the support, has at its upperend bifurcations 68 in alined openings 10 (Fig, 1) of .which a pin 12 is .rotatably .mounted Fitting between theibi furcations 68 and securedto the pin 12 by a pair of .lock screws 14 is a supporting. sleeve H5 in a bore18 ofwhich fits,a,shank portion 80 of a work carrier 82., Theshank portion. 80 has an opening 84 throughwhich extends the pin 12, the

- arrangement being such that thework carrier 82 may be rotated slightlyin the .bore 'l8.of .the

supporting sleeve I6 about an axis 83 of the the insole against the gage 96 and the bottom (the top in Figs. 2 and 3) face of the insole against pointed ends of the pins, swings the insole widthwise about its toe end until three holes [I00 (Fig. 3) formed in the insole arebrought into registration with the corresponding pins 92, the insole then being forced onto the pins. Simultaneously therewith the operator grasps the last I8 with his right hand and, by following the same general procedure above outlined in connection with the insole, causes the holes I02 formed in the bottom of the last to register'with the pins 92. A treadle rod I04 is then depressed to actuate a valve (not shown) whichadmits a suitable fluid, such, for example, as air or oil, to a hose I06 connected to .a cylindrical chamber I08 of-a housing I I0 forming part of the carrier,

thereby raising a presser member or clamp H2 in the chamber and thus forcingt-he forepart of the last I8 against theforepart of the insole 29 and the insole against the bottom'of the plate 88, the insole and the last thus being secured against movement in the carrier. As above stated, the holes I00, I02 in the insole 29 and the last I8, respectively, are so constructed and arranged that when corresponding holes in the insole and the last are in registration, as they are when mounted upon the pins 92,'as illustrated in Fig.- 2, the insole is accurately positioned upon the last.

When the machine i-s'idle, as illustrated inFig'.

1, the carrier 82 is held yieldin'gly in a horizontal of a spring II4 theupper end of which engages an arm IIB welded to thepin I2. The machine may thus be described as comprising yi'eldable means for maintaining the carrier 82 upon the support 50 in a predetermined idle position away from the fastening inserting mechanism 22.

After the work has been positioned and clamped in the machine, the operator grasps the last I8, in the manner illustrated in Fig. 2, and swings the carrier, together with the work clamped therein, upwardly about the axis I I8 of the pin I2 (the support 50 at this time remaining stationary) until the insole 20engages the trip lever 42 and then the nozzle 38, thereby actuating tack driving mechanism (not shown) to cause the first tack 40 (that is, the forwardmost tack shown in Fig. 3) to be driven through the insole and then through the opening 26 in the steel plate 24 and into the last I8. The opening 26 in the steel plate and the various holes I00, I02 in the insole 20 and the last I8,'respectively, are arranged in constant positions with relation to the toe end of the insole and the last irrespective of the size of the insole and thev last, the gage 96 being so positioned that the insole and the last may be quickly assembled upon the carrier, as above described, with the opening 26 arranged opposite the central portion of the U-shaped opening 98 formed inthe plate 88. It will be noted that in presenting the insole 20 to the nozzle 38 to'drive the first tack 40, the support 58 is not moved about the pin 48 since said support is so positioned by the stop 54 that when the carrier 82 is swung upwardly about the axis II8 of the pin I2, the nozzle enters the U-shaped opening 90 and is arranged opposite the opening 26 in the steel plate 24 so that the tack can be driven through the insole and into the last IB.

Preparatory to driving the second and third tacks 40 through the insole 20 and through the holes 21, 28, respectively, and into the last, the operator swings the carrier 82 about the axis I I8 of the pin I2 and the support 50 about pin 48, the

portion of the insole through which the tacks are to be driven being estimated by eye. It has been found that the operator soon becomes proficient in driving the second and third tacks and, if desirable, a fourth tack, through the holes 21, 28 and 29, respectively, in the plate 24 without mechanically guiding the carrier as in locating the position at which the first tack is driven. It will be noted that the holes 26 to 29, inclusive, formed in the last plate 24 are not exactly in alinement and that the operator, in carrying out the above operations, usually turns the upper portion 62 of the support, together with the carrier 82, slightly about the axis 64 (Fig. 2) with respect to the lower portion 66 of the support. Moreover, since the shank portion of the insole 20 in engagement with the bottom of the last is usually slightly convexed widthwise and it is desirable to drive the tack normal to the insole, the carrier 82, preparatory to driving the third tack into the insole, is sometimes tilted widthwise to a slight degree about the axis 83 of the shank portion 80 of the carrier.

The carrier 82, which is pivoted to the upper portion 62 of the support 50 about the axis II8 extending transversely of the last I8 and arranged in front of said last and approximately in the general plane of the forepart of the insole 20, may be described as mounted for swinging movement lengthwise, heightwise and widthwise of the last to move different portions of the insole successively to a position adjacent to the nozzle 38. It will be noted that the axis 64 (Fig. 2) is arranged at approximately right angles to the axes of the rod 48 and the pin 12, respectively, which are horizontally arranged and are parallel to each other, and that the axis 83 of the shank portion 80 of the carrier 82 is arranged at approximately right angles to a plane defined by the axes of said rod and pin.

After the tacks 40 have been driven through the insole 2i] and into the bottom of the last I8, the treadle rod I84 is lowered, thereby causing the presser member I I2 to be lowered in the cylinder I88. The last I8 and the insole 20 tacked thereto are then removed from the machine and the carrier 82 is moved back to its idle or starting position, the spring 55 causing the lower portion 66 of the support 50 to be moved againstthe stop 54 and the spring II4 causing the carrier 82 to be moved to its horizontal position and also causing it to swing about the axes B4 and 83 to the neutral position shown in Fig. 1.
